Environmental Chemistry of Nitrogen-Containing Organic Compounds in Biomass Burning Aerosols


EMSL Project ID
34933

Abstract

The objective of the proposed research is to advance fundamental understanding of environmental
chemistry of NOC present in BBA - the major sources of organic aerosols in the atmosphere. The proposed
research will address the following questions: a) What is the molecular composition of dominant NOC
compounds characteristic of primary BBA? b) What are the molecular markers specific to the NOC present in biomass combustion plumes? c) What NOC compounds of toxicological concern are present in the collected aerosol, at what concentration? d) Burning of what types of biomass produces elevated amounts of NOC and especially alkaloids e) What are the atmospherically-relevant mechanisms of NOC oxidative transformations?
